attempted to use PEM certificate with website and API, did not see any improvements or added functionality.
API -> https://jeap.rio.rj.gov.br/je-metinfosmac/portalV2/estacao. Website -> https://jeap.rio.rj.gov.br
- Provides raw values
- Provide lat,lng values for locations
- provides locations list
Hourly

API takes ~20 seconds to resolve
I attempted to use the cert provided on the website, but did not see any extra functionality with the website or efficiency with the API.
